Heat, in some cases. The wearing away of objects.
An example of undesirable friction is when a cyclists falls and his face against pavement that skin on the road. Undesirable friction is something that is not controllable.
When a car is travelling with brake pads rubbing although supposed to be free.
Ice skating.
Any bearing in your car's engine.
it is unwanted when you want to ride a bike and the tire rubs together to make it stop
In certain production of products , this will automatically save fuel and cost .
Wear & tear. Lower efficiency.
The force of friction between two objects is the product of the normal force and the coefficient of friction. The normal force is the component of force that is perpendicular to the plane of friction. For example, if you are pushing on a block of wood on the floor with a force F at an angle of 30 degrees above the horizontal, then the normal force N = F sin 30. The coefficient of friction is specific to the two materials, in this example the block of wood and the floor. In addition, there is a static coefficient of friction (applicable to a stationary situation) and a kinetic coefficient of friction (applicable when the object is already moving).

Friction plays a vital role in our daily life. Without friction we are handicap.1. It is becomes difficult to walk on a slippery road due to low friction. When we move on ice, it becomes difficult to walk due to low friction of ice.2. We can not fix nail in the wood or wall if there is no friction. It is friction which holds the nail.3. A horse can not pull a cart unless friction furnishes him a secure foothold.
Kinetic Friction replaces Static Friction when an object is in motion.

No You need friction to Walk, So the Answer Is False
friction in machines is undesirable becouse becouse the materials used to make them are always in griding form. ALLY S. MUBA-ngarambe
When one wants things to slide, move, or turn easily.
Pickle
A banjax is a mess or undesirable situation made as a result of incompetence.
Rotating bearings.
Desirable in scrummaging when the two packs form together. Without friction they would slip off which is dangerous. Friction is also desirable when making the tackle. And when sidestepping you need good grip. Undesireable when trying to evade the tackle.

Friction.
Figuratively, a camel's nose is a metaphor for a situation where the allowance of a small act will lead to a larger, undesirable act.
Ice skatingIn any electric motor. The friction causes the motor to heat up and waste energy.
